The Map of Romantic Kissing with Leaflet and R

Romantic kissing is a cultural universal, right? Nope! At least not if you are to believe Jankowiak et al.

So, with the help of my colleague Andrey Anikin I’ve now made such a map using R and the excellent leaflet package. Click on the image below to check it out:
